2 Claims. (01. 101-54) The present invention relates to a method of forming, refrigerating and harvesting water-ice, sherbet, ice cream, frozen custard and the like, in individual servings or units, each serving con- 5 sisting or a combination of'diiferent flavors of the same substance or of a combination of different substances; the servings being provided either with or without a handle member. The invention has particular relation to a new and improved method of and apparatus for making a plurality of such individualcomposite servings simultaneously in a most eificient, economical and sanitary manner.

Heretoiore, confectionery products have been 18 made in the form of individual servings consisting of various combinations of flavors and/or substances, but the disadvantages encountered in their manufacture with known methods have prevented their production on a large commercial 20 scale. Such confectionery products were made either entirely by hand molding. methods'and refrigerating the materials in an ordinary ice cream plant hardening room, or were formed by a moldlng operationin which a plurality of hollow shells 25 were made by various methods in multl-cavlty molds, and the hollow centers or openings in said shells were subsequently filled with another kind of substance orwith chopped fruits, nuts and the like. These methods had many disadvan- Butages, and were very laborious, expensive and section, of themold structure used in. forming the centers or cores of the composite servings;

Referring now to the drawings, there is shown in Fig. 1 a filling pan I, having upstanding sidewalls and end walls I 2, the latter having handles l3 mounted thereon for lifting and transporting the same. The pan I0 is provided with a plurality of spaced openings l4, arranged in two parallel rows and having integral tubular projections or filling tubes I6 extending downwardly therefrom, the tubes of one row being staggered with respect to the tubes of the other row.

The mold structure l1, shown in Figures 2, 3, 4,-

'5 and 7, consists of a pan I8, having upstanding sidewalls 2| and end walls 22, the latter being provided with handles 23 for raising and transporting the mold structure I1. The mold pan I! has a plurality of separate molds 24, adapted to receive material, depending therefrom and being formed integrally therewith. said molds 24 being spaced in two parallel rows with the molds of one row being staggered with respect to the molds of the other row. A rlmner .21 is mounted, by spot-welding or other suitable means, to the bottoms of the molds 24 of each row, upon which the mold structure is adapted to rest or be moved by sliding along the floor, table or 'other'support- The runners 21 are rigidly connected transversely -of the mold structure '|l by means of suitable brace rods 26. A metal band or bumper guard 23 is mounted around the lower ends of the molds 24, being securely welded to each of the molds 24,

46 for raising and transporting the same.

for bracing the lower ends thereof and to protect the molds 24 from being/damaged.

The rack or peg structure 3i, shown in Fig. 6,

consists of two spaced parallel bars 32 mounted Referring. generally to Figs. 9 to 12, inclusive, of

the drawings, there isshown a second mold structure 4|, which is similar in construction to the mold structure l1, except that the individual molds are larger in size and of a different ornamental shape. This mold structure 4| consists of a pan 42, having upstanding sidewalls 43 and end walls 44, the latter being provided with handles The mold pan 42 has a plurality of spaced separate molds 41 depending therefrom and being formed integrally therewith, said molds 41 being spaced in two parallel rows with the molds of one row being staggered with respect to the molds of the other row. Runners 48 are mounted on the bottoms of the molds 41, and are suitably braced with transversely extending brace rods 49. A metal band or bumper guard 5| is mounted around the lower ends of the molds 41, completely encircling the pendant molds of the mold structure 4| for bracing the same and providing protection for the molds 41 from damage.

The squeegee 50 shown in Fig. 15, consists of a rigid member 52, having an eliptical opening 53 in'the upper portion thereof to provided handle gripping facilities for manipulating the same, and a flexible rubber scraping edge 54 adapted for removing excess material from the mold and filling apparatus shown in Figs. 3, and 5.

The squeegee 56 shown in Fig. 16 is intended to be used in conjunction with the peg structure 3|, shown in Fig. 6, and consists of a rigid back member 51 having an eliptical opening 56 in the upper portion thereof -to provide handle gripping facilities for manipulating the same, and a flexible rubber scraping edge 59, having spaced inwardly extending slots 6| adapted to receive and engage the parallel bars 32 of the peg structure 3|, the bars forming a track for guiding the movement-of the squeegee 56 in leveling and removing the excess material from the second mold structure 4|, as best shown in Fig. 11,.

The multi-flavored or composite unitary serv ing '60, shown in Fig. 14 of the drawings, consists. of a central core formed with the upper portion 62 made of chocolate ice cream, and the lower portion 63 made of a fruit flavored ice cream having pieces of chopped fruits 64 therein, and then the entire core is covered ,with a layer of vanilla ice cream 66. It isobvious, however, that many different combinations of flavors may be used, or

shown in Fig. l in the molds shown in Fig. 2, as

illustrated in Fig. 3, and a quantity of chocolate ice cream 32 is placed in the filling pan H). The ice cream 82, when it is placed in the filling pan ill, is soft and semi-plastic or fluid, capable offlowing, andruns down into the filling tubes l6. After the tubes it are filled level with the top .of the pan it, a squeegee 58 is manually operated, as shown'in Fig.3, to force the ice cream 62 into any unfilled tubes andv to remove the excess cream that may have been deposited therein. The amount of ice cream deposited in the molds 24 depends upon the volume of the filling tubes i6, and may be varied by increasing or'decreasing the-size of the tubes l6 as desired.

When the filling apparatus is removed fromthe mold structure H, the ice cream or other material in the filling tubes it, being capable of flowing, will run out the bottom and fill the lower portion of the molds 24, as shown best in Fig. 4. The unfilled portions of the molds 24 are then completely filled by pouring another kin or fiavor of ice creamor other material, such as fruit ice cream 63 having. particles of chopped fruit M therein, into the mold pan iii of the mold structure i'i. This second kind or flavor of ice cream ti is likewise in a semi-fluid or plastic condition, substantially in the condition in which 1 ice cream is drawn from a standard ice cream freezer, but the viscosities of the two substances are such thatthey will not tend to intermix. The excess of the substance 63 is removed from the mold pan it and/or forced into any unfilled molds it by manipulation of the squeegee 58, as shown in Fig. 5.

When the molds M of the mold structure ill have been completely filled, the peg structure M of Fig. 6 h placed over the molds, the side and end walls of the mold structure i1 forming a guide for the ends 33 of the peg structure, thereby causing one of the pegs 38 to extend into each mold 2d and be centered therein. The mold structure it is then placed into a brine refrig crating tank 1|, having circulating brine 12 therein, and the mold structure i1 is permitted to remain in the brine tank ii until the contents t2 and ti of the molds 24 have become solidly frozen into an integral mass or core 12 and bonded to .the pegs it. The mold structure 91 and contents are removed from the brine tank i ii and momentarily placed in a defrosting tank it, containing warm water 16, which may be heated by any suitable means such as a gas burn-' er H, as best shown in Fig. 8. As soon as the bond between the frozen core 12 and the insides of the mold 124 is melted, the integral frozen masses or cores 12 are removed by lifting the peg structure ii by the handle members 84, thereby withdrawing the pegs 86 from the molds 24 with the cores bonded thereto. See Fig. 8.

While the mold structure i1 is in the refrigerating tank ii, the mold structure 4|, shown in centrally positioning each peg 38 and its core 12 over the molds 41. When the cores 12 are so lowered into the molds 41, they are submerged in the semi-fluid or liquid material 65 in the lower partthereof and thereby displace and force the liquid 65 up and entirely around the core 12 until the entire mold 41 is filled with material. By means of the squeegee 58, having slots 6| therein adapted to engage and ride on the top of the bars 32, as best shown in Figs. 10 and 11, the displaced material'is. smoothed out to form the bottom of the serving and the excess material may be removed from the mold structure 4|.

The mold structure 4| is next placed in a reirigera'ting" brine tank (not shown which is similar in every respect to the brine tank shown in Fig. 7, until the contents thereof are solidly frozen and congealed into a unitary mass or serving. 7 Upon removal of the mold structure ll from the brine tank, it is momentarily placed in a defrosting tank 8|, containing hot water 82, which is heated by means of gas fiames 83.,as shown in Fig. 12. As soon as the bond is broken between the servings 68 and the insides of. the molds 41, the former may be removed from the mold structure ti by lifting up on the peg structure 9|, the servings 89 still being bonded to the pegs 36 thereof. While the confections or servings 90 are bonded to the pegs 38, moisture proof paper bags t4 may be slipped over them. By this time the metal of the peg structure at has picked up enough heat from the room to weaken the bond between the pegs and the servings til so that the latter may be easily removed manually from the peg structure. Referring to Figs. 17 to 21 of the drawings, wherein I have shown a modified form of peg structure, wherein the pegs are removable from the structure and may be left in the finished servings to provide handle members therefor by which the servings may be held and manipulated while being eaten.

The modified form of peg structure 86, shown in Figs. 17 to 20, inclusive, consists of two spaced parallel bars 81 mounted between end plates 88, the upper ends of which are bent outwardly to provide handles 89 for facilitating manipulation of the structure. 1 The bars 81-of the peg structure d8 are provided with a plurality of spaced vertically extending openings 9|, which are adapted to receive removable pegs in the form of wooden handle sticks 92. The pegs 92 of the bars 81 are staggered to correspond to the spacing of the molds 24 and d1 of the mold structures l1 and M. The pegs 92 are securely fastened in the openings ti of the bars 81 by movable bars 93, slidably mounted on the tops of the bars 81 by screw bolts d4 operating in longitudinal slots 96. The bars 93 are moved with respect to the bars 81 manually by means of a handle 91 mounted adjacent one end thereof. The bars 93 are provided with a plurality of longitudinal slots 98 having anen-' larged portion 99 and a narrow tapering portion When the tion. The pegs 92 may be released from the peg structure 86 by merely moving the handle 91 to the left, which moves the bars .93 a corresponding distance to the left and br gs the enlarged portion 99 of the slots 98 overt e openings 9| in the bars 91 and at the same time forces the pegs 92 V stances to be frozen, subjecting the mold and out of the narrow slots IOI. The enlarged portion 99 of the slots 98 is too large to engage the pegs 92, and the weight of the servings illl which are bonded to the lower ends thereof, causes the pegs 92 to drop out of the peg structure 86. However, the pegs 92 being firmly bonded to the servings I04 remain therein and form handles by which they may be manipulated while being eaten. v

The method of making the modified serving I94 is identical with the method described for making the serving 69, except, however, thatthe peg structure 86 is substituted for the peg structure 3|, and when the peg structure 86 is removed from the mold structure 4 l with the unitary servings clinging to the pegs 92 thereof, the handle 91 of the peg structure 86 is moved to the left and the pegs 92 are released therefrom, the pegs 92 remaining in the frozen unitary and composite mass to form a handle member therefor.

Although I have not described a chocolate coated or other coated confection, it is obvious that any of the servings, either the handleless serving or the serving I94 which is provided without departing from the spirit thereof or from the scope of the appended claims.

What I claim is:-- v

1. The method of forming, refrigerating and harvesting a multi-fiavored unitserving, which comprises the steps of partially filling a mold with a substance to be frozen, filling the remainder of the mold with another kind of substance, positioning a. peg within the mold and into the subcontents to refrigeration until frozen into an integral mass and the substances bonded to said peg, removing the contents of the mold by means of said peg, positioning the same within a second mold containing a substance to be frozen, subjecting the second mold and contents to refrigeration until the latter is frozen into a unitary serving, and then removing said serving from the second mold by meansof said peg.

2. fl."he method of simultaneously forming, refrigerating and harvesting a plurality of multifiavored unitary servings which comprises partially filling a plurality of spaced molds with a substance to be frozen, completely filling said molds with a second substance to be frozen of a different character, placing a rod in each mold so that the rod extends through the second substance and the lower portion thereof extends into the first substance whereby the substances become independently bonded to the rods and to the mold walls when subjected to refrigeration, breaking the bonds between the substances and the mold walls, simultaneously withdrawing all of the rods with the substances bonded thereto, simultaneously immersing the substances so bonded to the rods into a second group of molds partially filled with a third substance to be frozen, subjecting the. second group of molds to refrigeration whereby the third substance becomes bonded to the rods, first and second substances and to the mold walls, breaking the bond between the third susbtance and the mold walls, and simultaneously separating all of the rods with the three substances independently bonded thereto from the second group of molds. l
